NFC-V (Vicinity)


NFC-V is the NFC communication technology based on ISO 15693,
extending NFC's reach from the typical 4 cm proximity range to vicinity distances of
up to 1-1.5 meters. The NFC Forum mapped NFC-V to Type 5 tags,
making it the bridge between short-range NFC interactions and longer-range RFID
applications.


Technical Characteristics


NFC-V operates with different parameters than the proximity protocols:






Parameter
NFC-V
NFC-A (comparison)






Base standard
ISO 15693
ISO 14443 A




Read range (dedicated reader)
Up to 1.5 m
Up to 10 cm




Read range (smartphone)
2-5 cm
2-5 cm




Data rate
1.66-26.48 kbps
106-848 kbps




UID
8 bytes (64-bit)
4 or 7 bytes




Memory block size
4 bytes
4 bytes (Type 2)




Subcarrier
Single or dual
Single






When read by a smartphone's NFC controller, NFC-V tags operate at the same short range
as other NFC tags because smartphone antennas are optimized for proximity operation.
The extended range only manifests with dedicated ISO 15693 readers that output higher
field strength.


Type 5 Tag Chips


Popular NFC-V / Type 5 chips include:


    

  • ICODE SLIX2 (NXP): 2560 bits user memory, password protection,
  privacy mode, EAS (Electronic Article Surveillance). Widely used in library systems.
    • 

  • ICODE DNA (NXP): AES-128 encryption,
  untraceable mode, cryptographic authentication for supply chain security.
    • 

  • ST25TV (STMicroelectronics): Tamper detection, configurable
  kill and privacy passwords, NDEF support.
    • 

  • ST25DV (STMicroelectronics): Dual-interface (ISO 15693 + I2C)
  for IoT sensor nodes. The I2C interface allows a connected microcontroller to write
  data that an NFC reader retrieves wirelessly.
    • 



Use Cases


NFC-V's combination of longer range and NFC smartphone compatibility makes it suitable
for several scenarios:


    

  • Library systems: Bulk checkout and anti-theft detection using longer-range readers.
    • 

  • Smart labeling: Product tags readable by both industrial ISO 15693 readers (at
  distance) and consumer smartphones (at touch range).
    • 

  • IoT sensor tags: Dual-interface chips like the ST25DV bridge
  wired sensor data to wireless NFC readout without batteries.

The NFC glossary is a comprehensive reference of technical terms, acronyms, and concepts used in Near Field Communication technology. It is designed for developers, product managers, and engineers who work with NFC and need clear definitions of terms like NDEF, APDU, anti-collision, and ISO 14443.

      

    

    
    

      
      

        
Each glossary term is cross-referenced with related NFC chips, standards, and other terms. For example, the term 'AES-128' links to chips that support AES encryption (NTAG 424 DNA, DESFire EV2/EV3), and the term 'ISO 14443' links to all chips compliant with that standard.

      

    

    
    

      
      

        
Yes. NFCFYI provides glossary definitions in 15 languages including English, Korean, Japanese, Chinese, Spanish, Portuguese, Hindi, Arabic, French, Russian, German, Turkish, Vietnamese, Indonesian, and Thai. Use the language selector in the header to switch languages.
